Here also according to definition of velocity, distance covered by object is nothing but the area of quadrilateral OPQS. Let this motion is represented by line AB in a s-t graph. Let us consider a body initially at S o is moving with constant velocity for time ‘t’ where it covers distance ‘S’. Third equation of motion can be obtained by slight modification in mathematical steps used in derivation of second equation. Fig: Displacement-time graph for uniform motion. (□OPQS) is combination of rectangle and triangle so that

OQ’ – OP = RQ = v – u = change in velocity First equation of motion:Īcceleration is defined as the change in velocity per unit time, then from graph, slope of line PQ can also represents the acceleration,Īccording to definition, velocity is rate of change of displacement hence,įrom the above equation, we can say that the displacement (from point P to Q) of object is nothing the area covered object in the quadrilateral OPQS When the slope of the distance-time graph is the same irrespective of the interval which is chosen, this indicates that the speed of an object under uniform motion remains. The speed can be calculated using the slope of the distance-time graph. In graph X- axis represents time and Y-axis represents velocity, When the distance-time graph is a straight line, then the motion of the object is said to be uniform. Where, u = initial velocity, v = final velocityĮquations of motion can be derived in various ways, but here we are going to derive them using the graphical method.Ĭonsider the body moving in XY plane starts its motion from point P with initial velocity ‘u’ (u≠0) and reaches to point Q in time ‘t’ with uniform acceleration ‘a’ and final velocity ‘v’ shown in figure below. The relation between initial velocity, final velocity and acceleration which are function of time can be given with the help of following equations which are, These equations are valid for uniform motion only. It is the maximum vertical displacement attained by the projectile.Hello dear, in this article we are going to illustrate the important tool to study the parameters of motion like initial velocity, final velocity, acceleration and time with help of some equations known as equation of motion. It is vector quantity and denoted by ($\overrightarrow$ 2. initial to final) is known as displacement. Describe (in words) what the car is doing during the experiment and what devices on the car must be utilized for the motion to occur. (easy) The graph below shows how a car moves along a straight road as a function of time. The shortest distance between any two points in specified direction. Click here to see the solutions to these problems. The distance of a moving body can be never be zero. The total length of actual path moved by an object from its initial position to final position is known as distance. Motion:Īn object is said to be in motion if it changes its position with respect to a reference point. Rest:Īn object is said to be in rest if it does not changes its position with respect to a reference point.

It does not give any information about force that causes it to move.

The branch of physics which deals with the study of motion as the function of time is known as kinematics.
